AUTOMATIC MYRIOSCOPE.

SPECIFICATION forming part of Letters Patent No. 676,445, dated June 18,1901.

Application nea November 7, 1900. serial No. 35,727. (No man.)

To all whom it may concern:

Be it known that I, ADoLPHUs PETERSON, a citizen of the United States,residing at Lansdowne, county of Delaware, and State of Pennsylvania,have invented a certain new and useful Improvement in AutomaticMyricscopes, of which the following is a specification.

My present invention relates to a new and useful improvement inautomatic exhibitors for carpet, wall-paper, and the like, and is what Iprefer to term an automatic myrioscope, and has for its object toimprove upon the construction shown in United States Patents Nos.606,236 and 607,073, granted to me June 2S, 1898, and July 12, 1898,respectively. With these ends in view this invention consists in thedetails of construction and coinbination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which@Figure 1 is a side elevation of a machine made in accordance with mypresent improvement; Fig. 2, a plan view thereof; Fig. 3, an enlargedlongitudinal section showing the mechanism for feeding the material tobe displayed looking from the side opposite to that shown in Fig. 1;Fig. 4, a section at the line of Fig. 2; Fig. 5, a plan View7 of one endof the machine, showing the trip mechanism for stopping the feeding ofthe material, so as to permit the samples to dwell for observation; Fig.6, a detail view showing the clutch and cam mechanism for bringing aboutthe automat-ic movements of the machine and Fig. 7, an enlargedlongitudinal. section similar to Fig. 2, showing a slightly-modifiedform of mechanism for reversing the travel of the sample-belt.

In carrying out my invention as here embodied, A represents theframework of the machine, which may be of any convenient design forsupporting the various parts, and on this frame is supported thedisplay-box B, whichk latter is rectangular, its inner walls beingcomposed of suitable mirrors C. This display-box is so arranged that thetra'veling sample-belt D passes thereunder, and when said belt dwells,as hereinafter described, the samples will be in a position to bereflected and multiplied in the mirrors C, thus giving a realisticappearance of a surface of indefinite extent covered with a material ofthe sample. Two feed-rolls E and E' are jour- ,naled in the frame andare provided with the flanges F and F', respectively, said iiangeshavingslots or openings G cut therein, in which the rods H are set, soas to move to and fro, and'to these rods are secured the ends of thedisplay-belt D for the purpose hereinafter set forth. Gear-wheels I andI are secured to these rolls and alternately receive motion from theactuating mechanism, as follows: The right-angle lever .I is pivotedconcentric with the 'roll E and has a pinion K journaled upon one armthereof, so as to always remain in mesh with the gearwheel I, while theopposite arm of this rightangle lever has'journaled thereon the pinionK', which always meshes with the gear-wheel l', so that to transmitmotion tovone or the carry one or the otherof the pinions K or K' intoengagement with the driving-gear L, which is accomplished by swingingthe rightangle lever for that purpose in the manner hereinafter setforth.

The driving-gearv L is journaled loosely upon the power-shaft M, andthis shaft in turn receives its motion from suitable pulleys N, securedupon its outer end and adapted vother gear-wheels it is only necessaryto to receive the belt, leading from a suitable source of power.

A hollow shaft O is mounted upon the dri ving-shaft M and carries aspiral cam P, which is free to Aslide longitudinally of the powershaftwithin certain limits and is normally held in one direction by thespring Q, inclosed in a suitable housing and bearing upon the outer endof the pin R, which in turn bears against the key R', set in the hollowshaft and sliding in the groove R2 in the powershaft. l

The driving-gear L has the pins Z upon its inner face, which constitutesone member of a clutch. The cam P has upon its outer face holes 2',corresponding to the pins l, and these represent the other member of theclutch.

IOS

S is a lever which is located upon one side of the machine and ispivotedat the point s to the frame of the machine. The inner end of thislever carries a tooth S', and this tooth is directly over and adapted tocome into cngagement with the cam-wheel P. The outer end of the lever Scarries a small roller S2. This roller S2 bears downward against the hubT, which is journaled loosely upon the counter-shaft U. This hub T hasupon its periphery a depression T'. A spring S2 is connected near theouter end of the lever S, and the other end of the spring beingconnected to some portion of the frame of the machine furnishes themeans of always holding the outer end of the lever S against the hub T.The counter-shaft U is adapted to' constantly revolve and receives itsmotion through the sprocket-wheel U', which is secured to the outer endofv this counter-shaft and the chain U2, which passes around asprocket-wheel U3, this sprocket-wheel U3 being journaled upon a shaftU1.

U5 is a large gear-wheel secured to the shaft U4, and this gear-wheel U5meshes with a small gear-wheel U6, which is secured to the power-shaftM. v Thus by reason of the difference in the relative sizes of the gearsU6 and U5 the counter-shaft U will receive a correspondingly slowmotion.

U7 is one member of a clutch secured to the counter-shaft U and adaptedto constantly revolve therewith. The hub T has upon its outer face teethto correspond with the teeth on the clutch U7, and thus constitutes thesecond member of the clutch. The hub T has formed with it the ange T2.This ange has upon its outer face the cam projection T3, while the hubis in engagement with the clutch member U7 and is revolved therewith.The cam projection T3 is adapted to come in engagement with the screwT4, which is secured in the frame of the machine, and thus will throwthe hub T out of engagement with the clutch member U7. The depression Tin the hub T is placed so that the roller S2 will drop within thisdepression at the same moment as the hub T is thrown out of engagementwith the clutch member U7. When this roller drops withinthe depressionT', the tooth S' upon the other end ot' the lever will be raised abovethe surface of the cam-wheel P, and this will allow the cam-wheel toslide longitudinally by reason 0f the pressure of the spring Q, and thuswill bring it into engagement with the driving-gear L. This drivinggearL will then be caused to revolve and will iu turn revolve either thegear-wheels K or K', whichever happens to be thrown into engagement withthe driving-gear L at the time, l

sired. These buttons are placed on the edge of the belt opposite to themechanism before At the junction ot' the samdescribed. XVy is a leverwhich is pivoted or, as I have shown it, secured to a spring XV', thisspring being in turn secured rigidly to the frame of the machine. Thislever is so placed that it will bear against the sample-belt as itpasses over the idle roll X, which is journaled loosely upon the shaftU, and this lever Wis directly in the path of travel of the projectionsV, so that when one of these projections V strikes the lever it willpress it outward, as shown in dotted lines in Fig. 2. The upper end ofthis lever WV passes through the outer end of a horizontal lever Z, andthis lever is pivoted at the point Z' to the cross-bar Z2, which extendsacross from and is secured to the two side frames of the machine. Thislever Z is shown in its normal position in Fig. 2, and when the lever Wis pressed outward by one of the projections V it will communicate themotion to the lever Z, which will then assume the posit-ion shown inFig. 5. The other end of this lever Z bears against a pin af, which issecured in the lever ct', and this lever is pivoted at the point cto thetop of the outer end of the lever S. This pivot d2 passes through thelever S and has secured to it underneath the small cam a2. Vhen thelever Z is forced into the position shown in Fig. 5 by means of theprojections V, it will cause the lever d and cam d3 to assume theposition shown in Fig. 5, and the point 'of this cam d3 bears againstthe inner face of the ange T2 upon the hub T, and thus will force thehub into j engagement with the other member of the clutch U7. Vhen thisoccurs, the hub T will be caused to revolve with the shaft U, and thiswill force the small roller S2 upward ont of the depression T' and causeit to travel around the periphery of the hub. When this end of the leveris so raised, the tooth S upon its other end will drop within one of the-threads of the cam or worm wheel P, and this worm, traveling in thedirection of the arrow shown in Fig. 4, will force itself out ofengagement with the pins Z upon the driving-gear L, and thus break theconnection between the train of gears which drives the belt. The beltwill then be stationary, so as to be viewed, until the hub T hasmade afull revolution and .the cam projection 'l`3 again comes in contact withthe screw T4 and forces the said hub out of engagement with the clutchU7, when the roller will drop in the depression, as before described,and raise the tooth S', so as to allow the cam-wheel P to engage thedrivinggear L. Thus the length of time that the belt of samples' isstationary and exposed to view will depend upon the relative size of thegears UG and U5 and the chain-wheels U' and U3.

b is an idle roll journaled at the opposite end of the machine to theidle roller X, and the belt is adapted to pass over the roller b, overthe table c and under the mirror-box, and over the idle roller X to theroller E.,

W'hen the belt of samples is entirely wound IOO IIO

upon one of the rolls, I desire to reverse the mechanism automatically,and this I accomplish as follows: In Fig. 3 I have shownthe belt ofsamples wound entirely upon the roll E', and the machine in operatingwill continue to wind the belt upon the roll E', and thus pull the rod Hto the outer end of the slots Gr in the iiange F of the roll E. This rodH ext-ends through the iiange and in revolving will come into engagementwith the lever d. This lever d is pivoted at the point d to the frameofthe machine. The upper end of this lever is adapted to come in contactwith the upper end of the upright member of the bellcrank lever J. Thiswill rock the bell-crank lever .I and force the gear-wheel K intoengagement with the driving-gear L and disengage the gear-Wheel K' fromthe gear L. This will then reverse the movements by communicating themotion to the gear-Wheel I of the roll E and render the roll E simply anidle roll. When the belt is entirely wound upon the roll E, thisoperation will be reversed by the rod H being drawn to the outer end ofits slot in the fiange F and coming in contact with the lever c, whichis pivoted at e to the -main frame, and the upper end of this lever ebears against and is adapted to rock the lever f. This lever f ispivoted concentric with the roll E. This leverf is connected to theupper end or upright member of the bellcrank lever J by means of thespring-linkje upon the outside of the side frame of the machine. Thislink is connected to the two levers by means of the screws f2, whichpass through slots f3 in the frame of the machine and are secured in thetwo levers. This link f is of spring metal and is adapted to bearagainst the frame of the machine, so as to cause a certain amount offriction therebetween, which will tend to hold the levers in whicheverposition they are forced. This Will make the machine entirely automatic,for when the belt has reached its limit in one direction it will reversethe mechanism and cause the belt to travel in the opposite direction,and so on as long as it is desired to opcrate the machine.

The operation of the intermediate motion for displaying the samples isas follows: We will begin and suppose that the sample-belt D isstationary and a sample 'is being displayed. Then roller S2 will beresting upon the periphery of the hub T and the tooth S will be holdingthe cam-wheel P out of engagement with the driving-gear L, so that the`will raise the tooth S from engagement with the cam-wheel P and allowthis cam-Wheel P to spring into engagement with the pins Zon thedriving-gear L, and as the cam-wheel P is constantly revolving this willcause the driving-gearL to revolve therewith and communicate to the gearK, and therethrough to the gear l, which has secured to it the rollE-that is, when the gears are in the position shown in Fig. 3. When theyare in the position shown in Fig. 7, the motion willbe communicated tothe gear K and therethrough to the gear I', which has the roll E securedthereto. This will cause either one or the other roll which is beingoperated upon to wind the belt thereupon, and this winding will continueuntil another sample is brought beneath the mirror-box C, and then oneof the projectionsV will pass underneath the lever W and force the sameoutward, and by doing so will communicate the motion to the horizontallever vZ, which will cause it to assume the position shown in Fig. 5,and this will cause the cam a3 to bear against the iiange T2 uponthe'hub T and press the teeth upon the outer face of the hub T intoengagement with the teeth upon the clutch member U7, and this clutchmember being constantly revolved will ccmmunicate motion to the hub Tand cause it to revolve therewith, which will force the roll S? upwardout of the recess T and cause the lever S to again assume the positionshown in Fig. 3, and the tooth S will thus be forced Within the threadsof the cam-wheel P, and this cam-wheel being revolved and being of thenature of a worm will force itself out of engagement with the pins Zupon the drivinggear L, and thus the movement of the gear will bearrested and the sample-belt will be caused to remain stationary untilthe shaft T has again madea revolution and forced itself out ofengagement with the clutch member U'7 and the roller S2 has againdropped within the recess T', when movement would be again commenced, asbefore described.

In Fig. 7 I have shown a slight modification of the manner of reversingthe movement of the sample-belt. edge of the sample-belt from thatwhereon is fastened the projections V, I secure at each end of thesample-belt a projection g, and upon each side oi' the machine and inthe line of travel of these projections I secure the levers h. Theseleversv are similar to the -lever W, which I use for arresting themovement of the sample-belt. One of'these levers is connected to thelever d by means of the link t', and the other lever h is connected tothe lever e by means of the link j. Thus when one of the projections gpasses'behind the leverh, as shown in Fig. 7, it will cause the lever eto be rocked, and thus rock the lever f and cause the gear K to meshwith the driving-gear L, as before described, and when the projection gcomes behind the other lever h it will cause the leverl d to be rocked,and

Upon the oppositeA IOO IIO

thus force the gear K into mesh with the driving-gear L, and thus againreverse the movement. As will be observed, in the iirstdescribed methodof reversing the samplebelt the sample-belt could not be reversed untilit had been entirely wound or unwound from either of the rollers; but inthe method last described the projections g could be set at any placeupon the belt, and whenever they strike the levers h the belt will bereversed. This would be very convenient, as at times certain samplesupon the belt might be soiled, so as not to be presentable, or for otherreasons it might not be desirable to show them. 'I hese two methods thatI have described for reversing the sample-belt might be used in amachine which was Vnot automatic as to the stopping and starting of.thebelt-that is to say, a machine that is adapted tobe turned by hand andthe belt stopped and started at will.

rollers would be one continuous strip, and the samples would be securedto this belt by being buttoned upon the same or in any other similarmanner, so that they could be con veniently removed and otherssubstituted.

Of course this machine need not necessarily be horizontal, as it couldbe used in any position, either horizontal, oblique, or perpendicular,without causing any change at all in the mechanical construction.

0f course I do not wish to be limited to the exact construction hereshown, as slight modiiications could be made without departing rfrom thespirit ot` my invention.
